How can i remove the property of required to the Second Element "Second Name" ?
Here is my Code :
<form action="#" novalidate>
First Name:
<input type="text" name="first" required>
Second Name :
<input type="text" name="second" required>
<input type="submit">
</form>
You can set required property to false
$("input[name=class]").prop("required", false);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form>
Name: <input type="text" name="name" required>
Class: <input type="text" name="class" required>
<input type="submit">
</form>
Using jQuery you can do:
$('input[name=second]').prop('required', false);
Example
Try using .removeAttr().
$('input[name="class"]').removeAttr('required')
Try this:
$('input[type="text"][name="second"]').prop('required', false);
it just removes the required property on the target element which has the name "second".
you can use the
removeAttribute command:
First set ID's for the inputs.
I set it to the same value as the name.
Next removeAttribute
document.getElementById("class").removeAttribute("required");
This should do the trick ;)

Hi guys i want to dynamically add a group of input fields when a button is pressed. This works with 1 group, but not with more than one. Here is my HTML:
<form action="address.php" method="POST">
<div id="list">
<input type="text" name="address" placeholder="Address">
<input type="text" name="suburb" placeholder="Suburb">
<input type="text" name="state" placeholder="State">
<input type="text" name="country" placeholder="Country">
<button id="addMore">Add Address</button>
</div>
</form>
I'm calling the addMore function with this javascript:
$(function(){
$("#addMore").click(function(e){
e.preventDefault();
$("#list").append("<input type="text" name="address" placeholder="Address"><input type="text" name="suburb" placeholder="Suburb"><input type="text" name="state" placeholder="State"><input type="text" name="country" placeholder="Country"><button id="addMore2">Add Address</button></div>");
});
});
I've added a button at the end with an id of addMore2 because i wanna generate a similar set of input controls but with different names. I want to call that id with this function:
$(function(){
$("#addMore2").click(function(e){
e.preventDefault();
$("#list").append("<input type="text" name="address2" placeholder="Address"><input type="text" name="suburb2" placeholder="Suburb"><input type="text" name="state2" placeholder="State"><input type="text" name="country2" placeholder="Country"><button id="addMore3">Add Address</button></div>");
});
});
... and then another set of controls with the function addMore3. Same as above, but with the number 3.
If i use each function alone, it works. But if i try to use all 3 together, it doesn't work. How can i dynamically reproduce a set of input controls with different names?
you could do something like this
$(var count = 0;
$("#addMore2").click(function(e){
e.preventDefault();
$("#list").append("<input type='text' name='address2'"+count+" placeholder="Address"><input type="text" name='suburb2'"+count+" placeholder="Suburb"><input type="text" name='state2'"+count+" placeholder="State"><input type="text" name='country2'"+count+" placeholder="Country"><button id='addMore3'"+count+">Add Address</button></div>");
count++;
});
});
#rayzor
You need to append your code before button
Please use below code:
jQuery("#addMore").click(function(e){
jQuery('<br><input type="text" name="address" placeholder="Address"><input type="text" name="suburb" placeholder="Suburb"><input type="text" name="state" placeholder="State"><input type="text" name="country" placeholder="Country">').insertAfter("input:last");
return false;
});
And remove code for $("#addMore2").click event
There's no need to add Addmore 2,3,etc manually. the js will add it automatically, as much as your want. Feel free to see this one: https://phppot.com/jquery/jquery-ajax-inline-crud-with-php/
I have a form field with the last name and want to generate a customer ID starting with the first two characters from their last name in caps and add a random number to it. So I need the other field which dynamically updates with only the first two characters in uppercase. This is what I have so far:
HTML:
<form action="#" id="form_field">
<input type="text" id="textfield1" value="" onKeyUp="document.getElementById('textfield2').value=this.value">
<input type="text" id="textfield2" value="">
</form>
JAVASCRIPT:
document.getElementById('textfield2').setAttribute('maxlength',2)
You can get the two first characters from your input and put them in the second with javascript :
<form action="#" id="form_field">
<input type="text" id="textfield1" value="" onKeyUp="document.getElementById('textfield2').value=this.value.substr(0,2).toUppercase()">
<input type="text" id="textfield2" value="">
</form>
I am not sure but I think that the javascript code don't care about the attribut "maxlength". Futhermore, you need use toUpperCase in order to have your result.
<form action="#" id="form_field">
<input type="text" id="textfield1" value="" onKeyUp="txt(this.value)">
<input type="text" id="textfield2" value="">
</form>
<script>
function txt(value) {
document.getElementById('textfield2').value = value.substr(0,2).toUpperCase();
}
</script>
hope it works
<form>
<p>
<label>Username</label>
<input name="username" placeholder="Username" required="" type="text">
</p>
</form>
<script language="JavaScript" type="text/javascript">
var username=$("#username").val();
</script>
I have read a lot of posts related to this problem, but I have not found solution.
I tried with Firebug and give me this:
username undefined
Where is the problem?
Because you don't have an element with the id "username". You have one with the name "username". So jQuery returns an empty set when you do $("#username") (as there are no matching elements). When you call val() on an empty set, it returns undefined.
You can either change your field to have an id:
<input id="username" name="username" placeholder="Username" required="" type="text">
Or change your selector to use the name:
var username = $("input[name=username]").val();
# is selector for ID, but you don't have ID on your input.
So you could add an ID:
<input name="username" placeholder="Username" id="username" required="" type="text">
Loot at this : Id Selector
try accessing element by name attribute:
$('input[name=username]').val()
or if you need to access by id, then add id attribute:
<input name="username" placeholder="Username" id="username" required="" type="text">
How to take content from a div class one by one and then load it into array? Then I need to insert these one by one to some other div class.
Basically, I have 2 forms, one of which is dummy and this dummy gets its content from CMS. The dummy form is hidden, while real form is shown, but empty at first.
I need to use jquery to take dummy text from form and insert it to real form.
Something like this:
<form name="real" method="post" action="">
<input type="text" name="first" id="a"/>
<input type="text" name="second" id="b"/>
<input type="text" name="third" id="c"/>
<input type="text" name="fourth" id="d"/>
<input type="submit" value="submit"/>
</form>
<form name="extract" style="display:none;">
<div class="generic">data_1</div>
<div class="generic">data_2</div>
<div class="generic">data_3</div>
<div class="generic">data_4</div>
</form>
must become something like this:
<form name="real" method="post" action="">
data_1 <input type="text" name="first" id="a"/>
data_2 <input type="text" name="second" id="b"/>
data_3 <input type="text" name="third" id="c"/>
data_4 <input type="text" name="fourth" id="d"/>
<input type="submit" value="submit"/>
</form>
Is there a way to do this?
Thanks!
There are many ways to do this. For example:
$('[name=extract] div').each(function(index){
$('[name=real] input:eq('+index+')').before($(this).text());
});

I'll offer this version:
$('.generic').each(
function(i){
$('input:text').eq(i).val($(this).text());
});

I'm using the jQuery .serialize function and can't get it to serialize the proper form on submit.
my js code:
function getquerystring(form) {
return $("form").serialize();
}
my forms:
<div class="leave_message_box">
<form name="leave_message_form">
<input type="text" name="clock_code" placeholder="Clock Code" />
<input type="text" name="message" placeholder="Message (Blank for none)"/>
<input type="hidden" name="type" value="leave_message" />
<input value="Leave Message" type="button" onclick='JavaScript:xmlhttpPost("clockin.php", "leave_message_form")'></p>
</form>
</div>
<div class="outside_job_box">
<form name="outside_job_form">
<input type="text" name="clock_code" placeholder="Clock Code" />
<input type="text" name="message" placeholder="Message (Blank for none)"/>
<input type="hidden" name="type" value="ouside_job" />
<input value="Outside Job" type="button" onclick='JavaScript:xmlhttpPost("clockin.php", "outside_job_form")'></p>
</form>
</div>
I must be doing something wrong in passing the variable. the full code # pastie. The function I have does work, however, its always the last form that gets submitted.
Using this code:
$("form")
will find all the <form> elements in your document.
Given that form is a string containing the name of the form, what you want instead is this:
$("form[name='" + form + "']")
Looking at your supplied code, I have this suggestion. Instead of passing the form name to your function, why not just pass the form itself?
<button onclick="xmlhttpPost('blah', this.form)">
You also don't need to put javascript: in the onclick, onfocus, onwhatever properties.
I would suggest putting an ID attribute on the form and then using that ID as an explicit selector for jQuery:
<div class="outside_job_box">
<form id="outside_job_form" name="outside_job_form">
<input type="text" name="clock_code" placeholder="Clock Code" />
<input type="text" name="message" placeholder="Message (Blank for none)"/>
<input type="hidden" name="type" value="ouside_job" />
<input value="Outside Job" type="button" onclick='JavaScript:xmlhttpPost("clockin.php", "outside_job_form")'></p>
</form>
</div>
Then you would select and serialize it like this;
var f = $("#outside_job_form").serialize();
Not only making your code more effecient but more readable, in my opinion.
If the sole purpose is to encode simple text into URL format then use encodeURIComponent().
